Dynamic Programming for Quantum Algorithm Design
Jincheng Zhang
Abstract
The design of efficient quantum algorithms frequently relies on intuitive heuristics and extensive trial-and-error processes. This research proposes a novel dynamic programming (DP) framework to systematically explore the vast space of potential quantum circuits, aiming to optimize both circuit structure and gate sequences based on computational cost and expected fidelity. The framework utilizes a bottom-up approach, building solutions from smaller subproblems, leveraging previously computed results to avoid redundant calculations. This approach contrasts with traditional, often ad-hoc, methods for quantum algorithm design. The core contribution lies in formally applying dynamic programming to this problem, providing a structured methodology for algorithm development that can potentially reduce the reliance on guesswork and accelerate the discovery of optimal quantum solutions. The presented framework incorporates key elements such as state representation, transition functions, and optimal substructure assumptions to guarantee efficiency and accuracy. This paper outlines the framework, its underlying principles, and potential applications within the broader field of quantum algorithm design.
